STOP
- Dieser Befehl bricht die Sprachausgabe ab und löst einen Reset des Synthesizers aus.
- Die Synthesizer-Einstellungen, Sprechgeschwindigkeit und APD Status bleiben erhalten. |
STOP
- This command forces the speech to stop and resets the synthesizing system.
- Synthesizing conditions, speech length and APD status are held by this command. |

SYSTEM POWER DOWN
- Stoppt den Taktgenerator des T6721A und reduziert den Stromverbrauch des gesamten Synthesizers.

SYSTEM POWER DOWN
- Stops oscillation of T6721A and reduces power to the entire synthesizing system.
- Places Audio Power Down output APD at "H" level.
- Places /ACL at "L" level and fixes the synthesizing system at the reset status. (Synthesizing conditions and speech length are also cleared, accordingly and reset is required when power is ON.) |

SYSTEM ASGIN
- Releases SYSTEM POWER DOWN status.
- After the release, there is the power on transient status for about average 30ms. /BSY is generated during this transient status.
- APD is kept at "H" level. Therefore, prior to starting speech, it is necessary to make AAGN shown below.
- It is necessary to take a time of more than 30ms before SAGN is made after SPDN. |

ROM READ MODE
- This is a command for setting a mode to read data in the voice data ROM. Under the normal mode other than this mode, the status is read by /RD.
- This mode is released when another command is written.
- The low order 4 bits of 8 bits of ROM data corresponding to ROM address that have been set by ADLD are taken into T6721A
by this command. These 4 bits are output to the bus lines D0-D3 by next /RD and at the same time, the high order 4 bits are
taken into T6721A. Address is advanced in order by the succeeding read and data is read every 4 bits.
- This function makes it possible to take other data than voice analysis data into the voice data ROM and use it (particularly effective for Phrase start address labelling). |

Ungenutzte Befehle
- Es gibt 4 ungenutzte Codes. Obwohl sie keine Wirkung haben, wird der Status "COMMAND ERROR" auf "H" gesetzt. |
Redundant Commands
- 4 types of redundant codes are available. Although there is no effect even when these redundant codes are read, the status "COMMAND ERROR" becomes "H" level. |
